Yellow Chopper over S.Shields

Hey i was just wondering if anyone else saw the black helicopter ( i think it was a dauphin, not too sure, it had retractable landing gear) with a yellow stripe along the fuselage and white underbelly.

It was flying east over South Shields (Near Newcastle) pretty low, i couldnt make out the name on the side but i was wondering if anyone knew what company it operated with and what it was doing there?. i think it was either on tuesday or wednesday afternoon.
